SAMUEL W. FISH, GF PLAINFIELD, NEVI JERSEY, ASSIGNOE TO TAYLOR IRON & STEEL COMPANY, OE HIGH BRIDGE, NEW JERSEY, A CORPORATION OE NEW JERSEY.

SAFE OR 'VAULT DOOR.

To all 'whom t may concern:

Be it known that SAMUEL W. FISH, a citizen of t-he United States, residing at Plainfield, in the county of Union and State of New Jersey, have invented certain new and useful improvements in Safe or Vault Doors, of which the following is a specilication.

The present improvement relates to safe or vault doors, the object thereof being to provide an improved door made up of a pair of members so united that each may engage the jamb surface and the inner member of which may constitute a back-plate for supporting the bolting or other operating means.

Tn the present improvementthe door is made up of a main door portion and a backplate for the support of the bolts and the operating means, the back-plate being united to the outer door by rotating one relatively to the other, another construction of the present improvement being illustrated in my contemporaneously pending application Serial No. 565,739, filed May 27, 1910.

Heretofore it has usually been necessary to secure the back-plates of doors made of umnachineable metal by means of bolts penetrating soft metal inserts in the door, this necessitating that the door holding bolts be carried by the inwardly extending flange of the door. By the present improvement, however, these bolts may be carried by the back-plate, since the improved manner of uniting the back-plate wit-h the door makes it practically impossible to separate the back-plate from the door by the action of explosives, thus obviating the necessity of forming bolt openings, or a bolt groove, in the body jamb, as the bolts may be so located that they can engage the inner surface of the inwardly extending flange or the body jamb, or any other portion ofthe body which may be in position to cooperate with the bolts, this depending entirely upon the construction of the body.

In the drawings accompanying and forming part of this specification, Figure 1 is a rear view of this improved door; Fig. 2

is a cross-sectional view thereof taken in line 2 2, Eig. 1; Fig. 3 is a perspective view of the inner member or back-plate of the door; and Fig. 4 is a perspective view of the outer member or main door portion.

Specification of Letters Patent.

Application led April 30, 191D.

Patented July 11, 1911. Serial No. 558,611.

Similar characters of reference indicate corresponding parts throughout the drawings.

rThe safe or vault body may be of any suitable form and construction, it having a tapered jamb 3 and is shown provided in the present instance with a plurality of shoulders or steps t and 5.

The door 6 comprises an outer member or main portion 7 and an inner member or back-plate 8, with a chamber 9 formed therebetween. In this chamber the bolt operating mechanism, or other necessary operating mechanism of the vault door, may be located and carried by the back plate, for which purpose, as hereinafter stated, the back plate is usually made of a metal different from that of which the outer member of the door is formed, so that it may be readily machined. These members are so united that each of the members forming` the door will engage the body jamb, and to permit this the main door portion is formed with a body portion 10 having an inwardly extending flange 11 spaced apart from the jamb and forming an annular recess 11, the wall of which is provided with a series of locking or holding lugs 12, the whole being formed of an integral structure and usually of some suitable unmachineable metal, as for instance manganese steel. The door is provided with a pair of steps or shoulders 13 and 14 adapted to engage the steps or shoulders of the body hereinbefore referred to.

rhe inner member or back-plate constituting the closure for the chamber of the main door portion formed within the inwardly extending iiange thereof, is provided with a flange 15 which may be considered as a forwardly extending flange, adapted to fit said recess and having a tapered outer surface adapted to conform to a portion of the tapered surface 1G of the body jamb, and this flange overlaps a portion of the inwardly extending flange of the outer or front member of the door and is also provided with a series of locking or holding lugs 17 adapted to coact .with the lugs of the inwardly extending flange of the outer door member, so that when one of the members is rotated with relation to the other they will be locked against separation except by rotary movement. Some suitable means, as for instance a lrey 01' keys 1.8, may be used to prevent the separation of the door members. 1n practice the inner member or back-plate may be made of a different metal from that of which the outer member of the door is formed, so that it may be readily machined for the reception of the bolts and bolt operating means, or any other form of door holding or locking means. rEhe inner member constituting the back-plate not only closes the chamber between the two members forming the door, but is, in the form shown, provided with a nair of annular flanges or rings 19, 2O forming a bolt carrying frame having a series of alined openings 21 for the reception of sliding bolts 22. The inner end of the flange forming the amb of the body may be provided with suitable bolt engaging surfaces for engagement with the door locking or holding bolts, and these surfaces may be located at intervals around the body flange, thus obviating the necessity of grinding the entire inner surface of the flange when the body is made of unmachineable metal.

From the foregoing it will be observed that the back-plate is not only secured to the outer member of the door in a very rigid manner, but it also constitutes a portion of the door and engages the jamb surface of the body, so that the separation or blowing off of the back-plate would be impracticable without the rupture of the entire door, while at the same time this back-plate, as hereinbefore stated, can be made of a different metal from that of which the outer member of the door is made, thus very materially lessening the cost as well as facilitating the construction of the door without in any way impair-ing its strength and efficiency, since, in order to separate the outer member of the door from the bach-plate, the lugs connecting the members would have to be entirely broken off, which is well nigh an impossibility.
